A plea deal has been reached in what was a first-of-its-kind case in St. Lucie County.
Accused drug dealer Rebecca Miggins was charged with attempted murder after a buyer overdosed in 2017.
The sheriff's office said Miggins sold straight fentanyl to a man who OD'd in a Fort Pierce motel and left without offering any help.
Deputies charged Miggins with attempted homicide during a specific felony, two counts of tampering with or destroying evidence, four counts of possession of a controlled substance without a prescription, three counts of possession of drug paraphernalia, and two counts of introduction of contraband into a detention facility.
Miggins has since agreed to a 13-year prison term and will not face the attempted murder charge.
"While we are pleased that this drug dealer who has no regard for another human's life will be removed from our community for 13 years, it saddens me that our legal system has mechanisms in place to allow for the mitigation of the seriousness of her actions," St. Lucie County Sheriff Ken Mascara said in a statement.
The sheriff went on to say his agency will continue to fish out drug dealers and send them to prison for as long as possible.
Florida is one of 20 states where it is a crime to provide or help obtain drugs that cause a death.
Miggins could have been sentenced to 81 years in prison.
She pleaded guilty to the sale and delivery of fentanyl and heroin and tampering with evidence.
Fentanyl is so dangerous, that when Miggins was brought in to the jail, it was discovered the seat tested positive for fentanyl and had to be removed from the patrol car.
